Title: Automatic film winder of camera
Inventor: YONEYAMA SABUROU
IPC: G03B1/00
Filed: 1979-11-19
Abstract: PURPOSE: To make it secure to wind a film automatically by providing a pressing member that winds the leader of a film by frictional force by increasing the diameter of a take-up member at one end part and then comes into contact with the take- up member slantingly.  
     CONSTITUTION: Narrow-width part A of the film leader fed into film take-up room 8 is pressed by pressing member 25 more strongly at the opposite side to its perforations (a), and consequently an influence of sprockets 4 which are to incline its advance direction to the opposite side to perforations (a) is canceled to wind the film in tight contact with the surface of external cylinder 13 of take-up member 9. Additonally, since take-up member 9 has external cylinder 13 greater in diameter at the side of perforations (a) of narrow-width part A of the film leader, the film is wound in tight contact even at the part, and eventually narrow-width part A is wound in tight contact with the surface of external cylinder 13 of take-up member 9 on the whole.

Abstract: PURPOSE:To produce the extremely thin and hard black plate at a high speed without generating a heat buckle by continuously annealing a cold rolled steel sheet consisting of an extra-low carbon steel thicker than the target thickness, then subjecting the sheet to temper rolling at the time of producing the extremely thin and hard black plate. CONSTITUTION:The extremely low carbon cold-rolled steel sheet which is produced by hot rolling and cold rolling a raw material steel slab to the thickness larger by about 25% than the final target value of 0.20mm and has <100ppm C is drawn out of a pay-off reel 1 and is welded by welder to the terminal end of the preceding steel sheet and thereafter, the surfaces are cleaned by cleaning equipment 4 at the time of producing the extremely thin and hard black plate having <0.20mm thickness and >T-4 degree of tempering. The steel sheet is then passed at >800m/min line speed in a continuous annealing furnace consisting of a preheating zone 6, heating zones 7, 8, a soaking zone 9, and a cooling zone 10 and is thereby continuously annealed. This steel sheet is temper-rolled at >=20% draft by >=2 stands of cold rolling mills 12.

Title: Logic circuit
Inventor: URAGAMI KEN
IPC: H03K19/0944
Filed: 1984-07-20
Abstract: PURPOSE:To make two contradictive characters such as reduction of power sonsumption and speed up etc. improve compatibly by controlling variably equivalent resistance value of a resistance element in a logic circuit by logical output. CONSTITUTION:When logical input in is H, a phase split step transistor TRQ2 becomes on, and logical output out becomes L, and FETM4 becomes off consequently. Thereby, equivalent value of a resistance element that forms load of collector side of the TRQ2 becomes high and power consumption is lowered. On the other hand, input in becomes H L, TRQ2 becomes on off and output out becomes L H. At this time, the FETM4 is changed from off to on the way the output out rises up from L to H. Thus, equivalent value of the resistance element that forms load of collector side of the TRQ2 becomes low in a moment. Consequently, change from L to H of the output out becomes sharp. Thus, characteristics of two contradictive characters can be improved compatibly.

Filed: 1987-06-16
Abstract: PURPOSE:To prevent a state wherein an abnormal current flows from being induced by providing a current detecting means and a current breaker to a current circuit made of a graphite tube, and putting the current breaker in operation when the output of the current detecting means exceeds a reference value. CONSTITUTION:When the temperature of the graphite tube 1 enters a high- temperature range, a switch 11 is switched from a contact (b) to a contact (a) with a signal from a temperature programmer 8. Consequently, a an error amplifier C2 is applied with a signal from a photodetector 9 and compares it with the signal from the programmer 8 and the output of the amplifier C2 is sent to a heating power circuit 4, thereby is controlled a tube current so that the output of the amplifier C2 is 0. At the same time, a signal from a current sensor 6 is also applied to a comparator C1, which compares the signal with the signal (reference voltage) from the programmer 8. When an overcurrent exceeding the reference value flows to a tube current circuit 3 due to a decrease in the resistance between both annular electrodes 2, the comparator C1 outputs the signal to operate the current breaker 5, thereby cutting off the current of the current circuit 3.

Title: Reflection type photomask and blank for that
Inventor: UEYAMA KOUSUKE
IPC: G03F1/50
Filed: 1994-06-30
Abstract: PURPOSE:To prevent the increase in the temp. of a reflection type photomask substrate having a reflection layer pattern on a substrate and to improve the accuracy of position of the exposed pattern by constituting the substrate of silicon carbide. CONSTITUTION:The substrate 1 of the reflection photomask having a reflection layer pattern 21 on the substrate consists of silicon carbide. By producing the supporting substrate 1 of silicon carbide to support the reflection pattern 21, the thermal conductivity is improved. Therefore, when short wavelength light is used for exposure (for example, i-line or an excimer laser such as KrF and ArF as the exposure light having shorter wavelength than g-line), and even when the light is absorbed to increase the substrate temp. (namely, the substrate is heated), the heat is rapidly conducted to escape outside of the member of the reflection type photomask and the substrate temp. is decreased. As a result, the warpage of the substrate and reduction of the accuracy of the position of the exposed pattern can be prevented.
